Working with files, Part 1: Reading | Smart Go

This video tutorial covers the basics of file handling in Go, focusing on reading files using Go version 1.16. It explains the use of three main packages: OS, IO, and Buff IO, each offering different levels of abstraction. The tutorial demonstrates reading a file's entire content into memory using the OS package and traversing a file line by line with Buff IO's scanner. It also shows how to load a file into memory as a collection of lines. The video concludes with a preview of writing files in Go.
